10 PULSAR MEASUREMENT

Functional Description Sludge Finder 2 sends a transmit pulse to the transducer, which then emits a high frequency ultrasonic sound wave perpendicular to the transducer face, the returned echo is received by the Sludge Finder 2. The time taken to receive the echo is measured and the distance from the transducer face to the sludge interface is calculated. The relays can be programmed to activate alarms, pump starters, or other control equipment. There is an isolated 4-20 mA output for each of two transducer channels that can be connected to a recorder or PLC to monitor the sludge interface independently from that shown on the display. Finally, there is an RS232 port, so that the Sludge Finder 2 can be operated remotely by a PC or other equipment to download/upload parameters or view real time echo traces. Sludge Finder 2 can be programmed either by the built-in keypad, or by PC via the RS 232 Serial Interface. All parameters are stored in non-volatile memory, so are retained in the event of power interruption. A second backup copy of all parameters can also be retained in the Sludge Finder 2 memory, in case an alternative set of parameters needs to be stored. Six user definable control relays with individual setpoints and intelligent performance logging software features ensure maximum control versatility. The Pulsar Sludge Finder 2 ultrasonic sludge detector has been designed to provide maintenance-free fit and forget performance.

When installing a transducer in a hazardous area use an approved transducer, from the Pulsar dB range, suitable for the proposed application.

ATEX For EEx m (Zone 1) applications a transducer certified to Sira 02ATEX5104X is used, and must be supplied via a 4000A breaking fuse, which is fitted as standard to the Sludge Finder 2 controller. For EEx ia (Zone 0) a transducer certified to Sira 02ATEX2103X is used, which must be connected to the Sludge Finder 2 via an external Zener barrier. See transducer label for certification details.

Important Information Please note that if the output of the ultrasonic transducers used with the Sludge Finder 2 are capable of emitting sound pressure levels in excess of 85dBA (above a reference sound pressure level of 20µPA), then the Sludge Finder 2 must be located remote from the transducer such that a sound pressure level of 85dBA is not exceeded when standing at the Sludge Finder 2 in the operator’s position.

22 PULSAR MEASUREMENT

Relay Outputs The six relays can be programmed for a variety of alarms or process control functions. The relay contacts are all rated at 5A at 115V AC. All connections should be such that the short circuit capacity of the circuits to which they are connected, is limited by fuses rated such that they do not exceed the relay rating. Current Output This is an isolated (floating) mA output (to 150 V), of 4 - 20mA or 0 - 20mA, and the load should not exceed 500 . RS2323 Serial Interface If required, you can connect to the serial interface to operate your Sludge Finder 2 remotely.

Important Information Never operate the Sludge Finder 2 with terminal access exposed. An external switch or circuit breaker should be installed near to the Sludge Finder 2 to allow the supply to be removed during installation and maintenance. In installations where the relay contacts have mains power connected, there should be a means of isolating them from the Sludge Finder 2. Interconnecting cables must be adequately insulated for IEC 664 Category II installations. Strip back 30 mm of the outer insulation of the cable. Strip 5 mm of insulation from the end of each conductor. Twist all exposed strands of the conductor together. Insert the stripped conductor into the terminal block as far as it will go and tighten the terminal block screw. Ensure that all strands are firmly clamped in the terminal block and that there is no excess bare conductor showing, and no stray strands.

Important Information If the equipment is installed or used in a manner not specified in this manual, then the protection provided by the equipment may be impaired.

SLUDGEFINDER 2 INSTRUCTION MANUAL

VT & ST (Sludge) Transducer Locating the Sludge Transducer • Position the transducer at a height within the tank such that it is fully submerged at all times that measurements are required, typically the face of the transducer should be 150mm below the normal water level. Liquid temperature compensation will only function correctly if the transducer is submerged at this level or below. • Ensure an unobstructed path between the transducer and the bottom of the tank. N.B. Rotating sub-surface rakes and scrapers, that pass beneath the transducer, do not interfere with normal operation. • Select a location that minimizes the presence of gas bubbles, high flow and heavy solid concentration dynamics in the process liquid near or the transducer. • Typical installation in a round clarifier or thickener is 1/3 to 2/3 the distance from the sidewall to the centre of the tank with transducer mounted from the walkway safety railing. • Typical installation in a rectangular clarifier or thickener is along the length of the clarifier in the third of the tank nearest the sludge discharge sump. Installing the Transducer • The transducer housing is designed to accept a 1-inch BSP female threaded coupler for pipe or conduit. Feed the integral transducer cable through the mounting pipe and tighten by hand until snug. CAUTION: extreme over-tightening may crack the transducer housing. • Position the transducer such that it is 150mm below the water surface and the mounting pipe is perpendicular to the water surface. Secure the mounting pipe in place with clamps to ensure that it is rigid. • Flexible arm transducers assemblies are available and are required where there is surface skimming equipment that passes the location of the transducer. Rotate the transducer mounting pipe so that the integral transducer shield contacts the skimmer arm squarely. Ensure that the transducer moves freely away from the passing skimmer equipment. • Optional transducer mounting brackets are available to extend the mounting pipe away from its connection point at the handrail to provide clearance from obstructions.

24 PULSAR MEASUREMENT

• If desired, the transducer cable may be extended up to 200m. Install transducer cables in grounded metal conduit. Do not run-in cable trays or duct banks with variable frequency drives or other high voltage sources. • Air (dB) transducers should be installed and connected in accordance with the installation instructions contained in the dB Transducer User Guide.

Wall mount Enclosure Locating the Sludge Finder 2 unit • The unit may be located inside a building or it may be field-mounted. • Locate the unit so that the maximum cable length to any transducer does not exceed 200m. • Avoid locating the processor near variable frequency drives or other high voltage equipment or cables. • Ensure that the Sludge Finder 2 controller is installed in a “Safe”, non- hazardous, area. • For a clear view of the LCD display it is recommended that it is mounted at eye level. • Ensure the mounting surface is vibration-free and the ambient temperature is between -20ºC and 50ºC. Installing the controller • Mount the unit at a convenient height for viewing the control panel and displays. Allow sufficient clearance around the unit for the door to swing fully open for instrument service. • Secure to a wall or panel using the mounting holes. Alternatively, attach to a local handrail using the optional Integrator Mounting Assembly.

Preparation for Operation Before switching on, check the following: ✓ The Sludge Finder 2 is mounted correctly and is in a ‘safe’ area. ✓ The power supply is correctly installed. ✓ The relays are connected correctly. Maintenance There are no user serviceable parts inside Sludge Finder 2, except the mains fuse. If you experience any problems with the unit, then please contact Pulsar Measurement for advice. To clean the equipment, wipe with a damp cloth. Do not use any solvents on the enclosure. VT & ST (Sludge)Transducer Maintenance. Procedure for the Removal of Transducers From time to time, it may be necessary to remove the transducer for cleaning or maintenance purposes, the following procedure is to ensure that this is done carefully with regard for the health and safety of the operator involved, and without damage to the transducer. The transducer mounting bracket (option 1) is designed such that the transducer can be removed without any parts being available to fall into the application. Before attempting to remove the transducer for cleaning or maintenance, the power to the unit should be disconnected. The correct PPE should be worn to ensure you do not come into direct contact with the wetted parts of the Sludge Finder 2 system, if in doubt contact your site Health and Safety Officer. To remove the transducer, loosen the retaining bolts on the end of the mounting brackets as shown in fig.1 and lift the transducer conduit assembly onto the walkway. The conduit is attached to the mounting assembly plate by means of a security chain so that it cannot be dropped and lost into the application. The transducer can then be safely inspected for damage or material fouling and can be carefully cleaned with a damp cloth to remove any foreign debris. Care should be taken not to move the wiper by hand as any movement not under the power of the motor may damage the unit.

27

SLUDGEFINDER 2 INSTRUCTION MANUAL

IMPORTANT WARRANTY NOTICE:

THE ONE YEAR TRANSDUCER WARRANTY IS VOID IF THE WIPER BLADE IS ROTATED BY HAND. THIS IS

DETRIMENTAL TO THE MOTOR GEAR DRIVE AND WILL DAMAGE THE UNIT.

28 PULSAR MEASUREMENT

The wiper arm on the VT10 will move twice every 20 mins as a default setting, if the face of the transducer is dirty and you are unsure as to whether or not the wiper is cleaning then place the transducer such that the wiper movement will not foul on anything and use the appropriate function key ( ) to force a wipe (see note below).

Important Information The function key will only initiate a wiper sweep on a VT transducer related to the currently viewed point and will only operate in run mode on the “Main” display. The function key will not initiate a wiper sweep if the dual point view is displayed.

If it is necessary to replace the transducer, the following procedure should be followed. Disconnect the transducer wiring from the electronics as shown on page 15 and remove the transducer cable from the electronics enclosure. The transducer is mounted onto the end of the conduit via its process fitting, this should be carefully unscrewed in an anticlockwise direction. Make sure the transducer is not dropped or knocked as this can damage the unit. When replacing the transducer care must be taken not to over tighten the unit as this can result in the transducer ‘ringing’. Hand tight is sufficient. When the transducer is replaced into the application and the power re- applied the unit will re-initialise and after a short period of time depending on the process conditions show the correct blanket reading.

CHAPTER 3 PULSAR RADIO TELEMETRY SYSTEM Some Pulsar units may be fitted with an optional Radio Telemetry System. This system cannot be retro fitted and must be purchased at the time of ordering. The system consists of a small transmitter board or ‘Node’ that is integrated into the SF2 housing and a receiver or ‘Gateway’ that is placed in a suitable location. The transmitter is pre-wired into the analogue output terminals and three of the digital outputs as shown below. TRANSMITTER (node) WIRING

The transmitter unit has two analogue outputs and two digital outputs. Channel 1 is mA OUT 1. Channel 2 is mA OUT 2. Relay 4 is DIG OUT 1. Relays 5 and 6 are DIG OUT 2 The mA output will be set by the user in the Application section of the parameters to reflect the operational 4-20 mA output span of the instrument. The Relays should be programmed as follows. Relay 5 should be set to be a Loss of Echo alarm, Relay 6 should be set to be a Wiper fail. These outputs are wired in series to DIG 2 and are used to give a Failure Output. Relay 4 can be programmed as a customer preference for Hi or Lo alarm output. 40 PULSAR MEASUREMENT

Installation Tips It is important to create a clear communication path. Wireless comms can be hindered by radio interference and obstructions in the path between the radio and receiver. To achieve the best performance carefully consider the installation locations for the Gateways and Nodes, select locations without obstructions in the pathway between them. Increase the height of the Antenna. Position the antenna vertically for optimal RF communication, if necessary, change the height of the radio or antenna to improve reception. For outdoor applications mounting the antenna on top of a pole or building may help to achieve line of sight radio link.

Be Aware of Seasonal Changes. Seasonal changes may affect signal strength, leaves on trees that were absent during a site survey can become a problem later in the year.

Node Gateway

A good signal strength in winter does not always mean you will get the same signal strength the rest of the year.

Further Antenna Installation Information. It is very important that the Radio Antenna is installed correctly for the Radio Communication to be reliable under all conditions.

Pulsar only supply External Antenna; these Antenna are weatherproof if installed correctly. Pulsar also supply 4m extensions for both the receiver and transmitter end to ensure there is sufficient flexibility for Antenna positioning. The Antenna always need a CLEAR LINE OF SIGHT to each other to maintain reliable communication, care should be taken if either the transmitter or receiver end is installed on moving machinery. Or, the installation takes place in winter and foliage growth during the summer months could block signal. Radio signal does not penetrate metalwork or water so special care should be taken avoiding these objects within line of sight. The 4m length of cable at each end should not be tightly coiled, care should be taken during the installation to ensure, if possible, the extension cable is run in such a way as to make extensive or tight coiling of the remainder unnecessary.

52 PULSAR MEASUREMENT

Bridge Integrator-Radio Schematic

The Integrator on the Bridge should be protected from the elements inside an enclosure, the Antenna extension cable should be installed through a cable gland in the base of the enclosure and out to a suitable position so that the Antenna is above the enclosure. If the installation position at either end is thought to be susceptible to a lightning strike then a surge suppressor can be installed in place of the cable gland, this installation would require an additional small extension cable from the integrator to the surge suppressor which is a bulkhead fitting. Please contact Pulsar for details.

HOW TO USE YOUR SLUDGEFINDER 2 Operating the Controls Display The graphical display provides four levels of runtime information and a sophisticated, progressive menu system in program mode. While in Run Mode, the ‘Main’ screen displays the current level reading and its units of measure, with a graphical representation of level for point 1 and/or point 2 along with status information with regards to the Transducer, Echo reception, Wiper status and Fail Safe Mode via the hotkeys. To scroll between run mode screens, use the left and right arrow keys (see diagrams below). To switch between points, use the up and down arrow keys. The ‘Echo’ screen shows the live echo trace of point 1, point 2 or both on the same screen, with various viewing options described later in this chapter. The ‘Range’ screen gives details of the empty level, span and blanking for point 1 or point 2. The ‘Relays’ screen gives live information on relay type and current state, a graphical representation of on and off setpoints and the current level for point 1 or point 2. When in Program mode, the display is used to read information on the menu system, parameter details and the values that can be entered. During Test Mode the display is used to monitor the simulated level with a screen like the ‘Main’ screen in Run Mode. The current test mode (auto/manual hard/soft) will also be shown at the bottom of the screen. There are two main operating modes for your Sludge Finder 2, Run Mode and Program Mode. There is also a Test Mode, used for checking the set- up. All modes are now described.

55

SLUDGEFINDER 2 INSTRUCTION MANUAL

Run Mode This mode is used once the Sludge Finder 2 has been set up in program mode. It is also the default mode that the unit reverts to when it resumes operation after a power failure. When Sludge Finder 2 is switched on for the first time, it will display, in metres, a level measurement relating to the default tank dimensions. All relays by default are switched off. After programming is complete, any relays that are set will operate when the level reaches the relevant setpoint, and the LED’s will change colour (unless specifically switched off). Main This group of screens provides information on Point 1, Point 2 or an overview of both Points. Use the up and down arrows to scroll between points 1, 2 or both. Below is an example of point 1, this is the screen that will be displayed when the Sludge Finder 2 is switched on for the first time.

There are two means of editing parameters, directly or using the menu system. Each is now described. Using the Menu System The menu system has been designed to make the changing of parameters very simple. There are two levels of menu: Main Menu and Sub Menu. At the top of the display there is a line of text that displays the main menu items. Pressing the left/right arrow keys scrolls the display between the top- level menu items, (as the example shown below, starting at Application).

*This is only available in units with firmware version 1.1.0 or greater As you press the cursor keys to scroll left and right between these, you can press ENTER, or the down arrow, at any time, to expand the sub-menu. Each menu options, along with their sub-menus, is described later in this manual. When you move down into the sub-menu, you can scroll up and down using the arrow keys and then press ENTER to go to the required parameter lists. If there are more menu options or parameters than can be viewed on the display in one go, then a scroll bar will appear on the right hand side of the menu/parameter box. The position of the solid bar within the scroll bar provides a visual aid as to your position in the current menu.

Scroll bar Parameter List

Highlighted parameter Scroll bar position

64 PULSAR MEASUREMENT

Once you have reached the relevant section, scroll down the parameter list to highlight the parameter you wish to edit, and press ENTER to access the parameter options. When you are at parameter level, the options for that parameter will be displayed on the screen. If the parameter has pre-set options then scroll up or down, with the up/down arrow keys, or press the designated number key (displayed on the left hand side) to highlight the option, then press ENTER to save. If the parameter requires you to enter a value within a particular range, the range options will be displayed with a box to enter the value. Use the numeric keypad to enter the required value following the onscreen prompts and press ENTER to save. When you have finished, press CANCEL to go back to the previous menu level. When you have reached the top level, press the CANCEL button again, the Sludge Finder 2 will ask for confirmation before allowing you return to run mode. This is done by pressing ENTER at the display prompt.

Directly Editing Parameters If you already know the number of the parameter, that you wish to look at or edit, simply type the number in at any time while you are in the menu system. Thus, if you are in either the menu or sub-menu level by pressing a numeric key, you can enter the parameter number directly and jump straight there. You cannot type a parameter number whilst at parameter level, only at one of the two menu levels. When you are at a parameter, the text line rotates automatically displaying the parameter name, number, the applicable units, and the maximum and minimum figure you can enter. The top line shows the value you are setting. Once you have accessed a parameter, you can either just look at it, or change it. Once a parameter has been changed, press ENTER and you will see the parameter value changed in the parameter list. If you press CANCEL then you will be returned to the parameter list with no change to the values.

SLUDGEFINDER 2 INSTRUCTION MANUAL

Test Mode Test mode is used to simulate the application and confirm that all parameters and relay setpoints have been entered as expected. During simulation, there is a choice of whether the relays will change state (hard simulation) or not (soft simulation), but the LED’s will always change colour as programmed, and the mA outputs will change in accordance with the chosen mode of operation. If you wish to test the logic of the system that the relays are connected to then select hard simulation, but if you don’t wish to change the relay state, then select a soft simulation. There are two modes of simulation for each point of measurement, automatic and manual. Automatic simulation will move the level up and down between empty level or the pre-determined Start Level (P983) and the span, if you wish to change the direction of the level movement, this can be done by using the left/right arrow keys. In manual simulation, using the up/down arrow keys will allow you to move the level up and down as required. To enter simulation, first go to program mode. Using the menu system, select menu item ‘Test’, then sub-menu item ‘Simulation’. Select the point of measure you wish to simulate and press enter to access the simulation options. You can change the value of the parameter to one of the following: 1= Manual soft simulation 2= Automatic soft simulation 3= Manual hard simulation 4= Automatic hard simulation When in test mode, the display will show the graphical level indicator with the current mode of operation value in measurement units. Also shown will be the relay setpoint indicators, for each relay, with an arrow showing the current level relevant to that relay allocation e.g. if you are simulating point 1 then the level indicator will move up and down along with the arrows next to any relay allocated to point 1. If a relay is allocated to sum, average or differential, then the Sludge Finder 2 will span the relay diagram to the sum, average or differential of point 1 and 2. The level of point 2 (or point 1 if simulating point 2) will always remain at 0. To return to program mode, press CANCEL and test mode will end.

66 PULSAR MEASUREMENT

When in manual simulation, by default test mode will move the level by 0.1m steps. Altering the increment (P981) will change this value. In automatic mode, the rate at which the level moves up and down is set by the increment (P981 in metres, the rate (P982) in minutes, which can be changed to make the level move up and down faster. E.g., if increment (P981) is set for 0.1m and rate (P982) is set to 1 min then the level will increase or decrease at a rate of 0.1m/min. To make the simulated level move slower, decrease the value in increment (P981) or increase the value in rate (P982). To make the simulated level move faster, increase the value in increment (P981) or decrease the value in rate (P982). Using the Serial Interface The RS232 serial interface is used to communicate between the Sludge Finder 2 and a PC using the optional Sludge Finder PC software and other associated Pulsar software packages. To obtain information such as data logging and view echo traces, upload, download and save parameter files. In addition it can also be used to control or obtain information using a standard PC or other computer base equipment. To do so, the default settings for communications port are as follows: baud rate 19,200, 8 data bits, no parity, 1 stop bit. The device should be connected as shown in Chapter 2 Installation. To use the device remotely, you need to log on to start, and log off when finished. When logged on, Sludge Finder 2 will show “Remote” on the display in place of the clock. When logged off, the display will return to normal (clock will be displayed). All commands should be followed by a carriage return. The unit will respond either OK or a value if the command is accepted, or NO if the command is not recognised or is not available. To log on, send the command /ACCESS:pppp where pppp is the passcode (P922). To log off, send the command /ACCESS:OFF To set a parameter, send the command /Pxxx:yy where xxx is the parameter number, and yy is the value you wish to set it to. 67

SLUDGEFINDER 2 INSTRUCTION MANUAL

Other commands you can use are: /DISTANCE 1 (shows current distance of point 1) /DISTANCE 2 (shows current distance of point 2) /LEVEL 1 (shows current level of point 1l) /LEVEL (shows current level of point 2) /TEMP1 (shows current temperature of point 1) /TEMP2 (shows current temperature of point 2) /CURRENTOUT1 (shows the mA output value for mA output 1) /CURRENTOUT2 (shows the mA output value for mA output 2)

Parameter Defaults

Factory Defaults When first installing the Sludge Finder 2, or subsequently moving or using the unit on a new application, before proceeding to program the unit for its intended application it is recommended that you ensure that all parameters are at their default values by completing a Factory Defaults P930, as described in the parameter guide.

When you first switch Sludge Finder 2 on, it will be reading the distance from the face of the transducer to the interface. It will be indicating in metres, as shown on the display and all relays are set OFF. The date (P931) and time (P932) in Sludge Finder 2 were set at the factory, but may need checking, and amending if, for example the application is in a time zone other than GMT, see relevant unit Parameter listing for full details. Once you are satisfied with the installation, and Sludge Finder 2 is reading what you would expect in terms of distance from the face of the transducer to the material level, then you can proceed with programming for the intended application. It is sensible to program all of the required parameters at the same time. The system will then be fully set-up. Once you are satisfied with the installation, and the SludgeFinder 2 is reading what you would expect in terms of distance from the face of the transducer to the material level, then you can proceed with programming, for the intended application. It is sensible to program all of the required parameters at the same time. The system will be then set-up.

Note: The span is automatically calculated from the empty level, so the empty level should be entered first.

Setting Up Point 2 with as an Ultrasonic Point of Measurement If it is required that point two is to be set up as an ultrasonic transducer to measure level in air, follow the procedure as per the example below.

Example 2: Level Monitoring with High and Low Alarms on Point 2 A vessel, containing a liquid that has a variation in level that is to be monitored, with a high level alarm set on Relay 1, and low level alarm set on Relay 2. The following method uses an air transducer from the dB range, example shown is a dB6 on channel 2.

Empty Distance (P1105), 3.5m

100%. Span (P1106), 2.8m

85%. High alarm on (P223), 8.5 2.38m 80%. High alarm off (P224), 2.24m

15%, Low alarm off (P234), 0.42m

10%. Low alarm on (P233), 0.28m

0%, Empty level

In this example, when the level rises to 2.38 m, relay 2 will come on until the level drops to 2.24 m when it will turn off. If the level drops to 0.28 m, then relay 3 will come on until it rises 0.42 m when it will turn off. The display for point 2 will show the level in the tank. The mA output will be representative of level where 4mA = empty level (0%) and 20mA = 2.8m (100%).

Example 3: Using a Single Viper Transducer to Measure 2 Different Interface Levels. The Pulsar SF2 Integrator can be used to monitor both the Rag or FLOC levels and the Settled Sludge or RAS levels simultaneously using only one Viper Transducer. This feature gives the user the ability to monitor and control the RAS level application by monitoring the settled sludge, but also prevent damaging FLOC spillage to the local water course by monitoring the less dense Rag levels. To achieve this, we utilise Point number 2 in addition to Point number 1. Both points will display the same profile, but different service parameters can be applied thus setting Point 1 to monitor the RAS layer and Point 2 the FLOC layer. It is required to set Point 2 Allocation in the Application menu (P1103) To 0 = Transducer 1.

The above profiles show the unit differentiating between the two echoes. In this instance point one is set to pick the largest echo and point two is set to pick the first echo (see SF2 Service Manual for details). Each 4-20ma can be independently set to track both interfaces. All relays can be independently set to give control or alarms on both points.

76 PULSAR MEASUREMENT

Example 4: Setting the Unit to Alarm on Hi-Floc Levels

High Floc Alarm The unit is now able to pick up on high level of floc readings, to do this it reacts to the raw echo trace rather than the processed echo. You are then able to set an alarm that is only reacting to the raw floc levels which will activate if the % of intrusion (P163) is reached between the distances set (in measurement units) in P160 Start distance and P161 End Distance. So if the reading is low and sat near the bottom of the tank the processed echo is low but the raw echo can be high. The unit will pick up hi levels of floc near the surface which it can only do by looking at the raw trace. The alarm On Delay P164 and Off Delay P165 can be set to prevent passing ‘clouds’ of material in flight from nuisance alarming. With the introduction of the High Floc Alarm feature, several different parameters and features now need to be included into the manual. Below are the illustrations, parameters and their descriptions which require adding to the new release of manuals due to be compiled indicating how to program a high floc alarm.

CHAPTER 7 PARAMETER LISTING AND DESCRIPTION Application Parameters Point 1 / Point 2 P1-100, P2-1100 Mode of Operation This parameter sets the mode of operation, when in run mode, and can be set to one of the following: OPTION DESCRIPTION Display shows the distance from the transducer face 1 = Distance (Default) to the surface of the material measured. 2 = Level Shows how full a vessel is. 3 = Space Shows how empty a vessel is. 4* = Average Level P1 & P2 Display shows the average level of point 1 & point 2 Display shows the differential between point 1 & 5* = Differential P1 & P2 point 2 *If transducer 2 is enabled

P1-101, P2-1101 Xducer (Transducer) This parameter should be set to the transducer being used with the unit, and can be set to one of the following: OPTION DESCRIPTION 0 = None For point 2 only. Disables point 2 (Default) 1 = dB3 Transducer is a dB3. Range = 0.125 to 3 metres 2 = dB6 Transducer is a dB6. Range = 0.3 to 6 metres 3 = dB10 Transducer is a dB10. Range = 0.3 to 10 metres 4 = dB15 Transducer is a dB15. Range = 0.5 to 15 metres 5 = dB25 Transducer is a dB25. Range = 0.6 to 25 metres 6 = dB40 Transducer is a dB40. Range = 1.2 to 40 metres 7 = VT10 (Default) Transducer is a VT10. Range = 0.3 to 10 metres *8 = ST10 Transducer is a ST10. Range = 0.3 to 10 metres

*This option is only available in firmware versions 2.2.0 and greater

92 PULSAR MEASUREMENT

P1-102, P2-102 Material This parameter should be set to the type of site being monitored for Sludge or the material being monitored with air transducers. The options are: VT/ST Transducer OPTION DESCRIPTION 1 = Industrial Use for the majority of non-sludge sites 2 = Primary (Default) Use for primary settlement tanks 3 = Secondary Use for secondary settlement tanks 4 = SBR Use for SBR (Sequencing Batch Reactor) tanks dB Transducers OPTION DESCRIPTION 1 = Industrial Use for the majority of non-sludge sites 2 = Primary (Default) Use for primary settlement tanks

P1-P105, P2-P1105 Empty Level (dB transducers only) This parameter is to be set to the maximum distance from the face of a dB transducer to the empty point (bottom of tank), in P104 Measurement Units. This value also affects span, (see important information below), so should be set before span. With sludge transducers, the empty level is automatically calculated from P115 Tank Depth and P116 Transducer Depth. P1-P106, P2-P1106 Span This parameter should be set to the maximum distance from the Tank Depth (P115/P1115) or Empty Level (P105/P1105) to the maximum material level. It is automatically set to be equal to the Tank Depth (P115/P1115) or Empty Level (P105/P1105) less the Near Blanking distance (P107/P1107) when you set the tank depth or empty level.

93

SLUDGEFINDER 2 INSTRUCTION MANUAL

Important Notice When changing the Tank Depth (P115) or Empty Distance (P105) you can also recalculate the values for the Span and the Relay Setpoints to take in to account the near blanking (P107) and transducer depth (P116) where applicable, so that they remain at the same percentage values of the empty distance as they were before they were changed. The question “Recalculate Span?” will be asked, if you choose yes (enter), then the span will be recalculated, any other answer will leave the span at its original value. You will then be asked if you want to “Recalculate Setpoints?”, if you choose yes (enter), then all Relay Setpoints will be recalculated as a percentage of the new empty distance, any other answer will leave the setpoints at their original values.

P1-107, P2-1107 Near Blanking This parameter is the distance from the face of the transducer that is not measurable and is pre-set to the minimum value dependant on the Transducer (P101) selected. It should not be set to less than this figure, but can be increased, typically to ignore close in obstructions. TRANSDUCER NEAR BLANKING DISTANCE P101/P1101 = dB3 Default blanking distance = 0.125 metres P101/P1101 = dB6 Default blanking distance = 0.30 metres P101/P1101 = dB10 Default blanking distance = 0.30 metres P101/P1101 = dB15 Default blanking distance = 0.50 metres P101/P1101 = dB25 Default blanking distance = 0.60 metres P101/P1101 = dB40 Default blanking distance = 1.20 metres P101/P1101 = VT10 Default blanking distance = 0.30 metres *P101/P1101 = ST10 Default blanking distance = 0.30 metres

*This option is only available in firmware versions 2.2.0 and greater.

P1-108, P2-1108 Far Blanking Distance This is the distance (as a percentage of empty level P105) beyond the empty point that the unit will be able to measure, and by default is pre-set to 20% of the empty level. If the surface being monitored can extend beyond the Empty Level (P105) then the far blanking distance can be increased to a maximum of 100% of empty level. This parameter is always entered as a % of empty level.

106 PULSAR MEASUREMENT

Display Parameters Point 1 / Point 2 P1-800, P2-1800 Display Units This parameter determines whether the reading displayed is in Measurement Units (P104), or as a percentage of span. OPTION DESCRIPTION Display is in selected unit’s dependent in Mode 1 = Measured (Default) (P100/P1100) Display is in percentage of span dependent in Mode 2 = Percentage (P100/P1100) P1-801, P2-1801 Decimal Places This parameter determines the number of decimal places on the reading during run mode. Minimum = 0 (No decimal places), Maximum 3 = (3 decimal Places). Default = 2 (2 decimal Places). P1-802, P2-1802 Display Offset The value of this parameter is added to the reading before it is displayed, in Measurement Units (P104). It does not affect the relay setpoints or the mA output, only the reading on the display. You could use this feature if for example you wanted to reference the reading to sea level, where you would enter the distance between Empty Level (P105) and sea level. If the empty level point is below sea level, then enter a negative value. P1-804, P2-1804 Display Conversion The reading is multiplied by the value of this parameter before being displayed. The default is 1.0, but if for example you wanted to display the reading in yards, then set the Measurement Units (P104) to feet and set P804 to 3.

107

SLUDGEFINDER 2 INSTRUCTION MANUAL

Failsafe P1-808, P2-1808 Failsafe Mode By default, if a fail-safe condition occurs, then the display, relays and the mA output are held at their last known values until a valid reading is obtained. If required, then you can change this so that the unit goes to high (100% of span), or low (empty) as follows: OPTION DESCRIPTION 1 = Known (Default) Remain at its last known value 2 = High Will fail to the high value (100% span) 3 = Low Will fail to the low value (empty)

See Also P218, P228, P238, P248, P258, 268 - Relay Fail-safe and P840 mA Output Fail- safe

Important Notice In the event of a fail-safe condition occurring, the display, relays and mA Output can be configured to fail to a condition which is independent of each other. To set independent Relay Failsafe see P218, 228, 238, 248, 258, 268. And for independent mA Output Failsafe see P840/P898.

P1-809, P2-1809 Failsafe Time In the event of a failsafe condition the failsafe timer determines the time before failsafe mode is activated. Default = 2mins If the timer activates, the unit goes into failsafe, as determined by P808/P1808 (Display), P218, 228, 238, 248, 258, 268 (Relays) and P840/P898 (mA Output). When this happens, you will see the message “Failed Safe!” on the display, along with a message explaining why (lost echo or transducer fault, for example). When a valid measurement is obtained then the display, relays and mA output will be restored, and the timer is reset.

P823 Totaliser Multiplication Factor This parameter determines the number of decimal places in the totaliser during run mode. It can be set between 1 and 3. Default = 2

108 PULSAR MEASUREMENT mA Out 1 / mA Out 2 Parameters P1-830, P2-1830 mA Range This parameter determines the range of the mA output, from the following: OPTION DESCRIPTION 0 = Off mA output disabled mA output directly proportional to the mA mode 1 = 0 to 20 mA (P831,891), so if the reading is 0% the output is 0 mA. If the reading is 100% the output is 20 mA. mA output directly proportional to the mA mode 2 = 4to 20 mA (P831,891), so if the reading is 0% the output is 4 (Default) mA. If the reading is 100% the output is 20 mA. mA output inversely proportional to the mA mode 3 = 20 to 0 mA (P831,891), so if the reading is 0% the output is 20 mA. If the reading is 100% the output is 0 mA. mA output inversely proportional to the mA mode 4 = 20 to 4 mA (P831,891), so if the reading is 0% the output is 20 mA. If the reading is 100% the output is 4 mA.

P1-831, P2-1891 mA Mode This parameter determines how the mA Output relates to what is measured. By default, it operates the same as the display (P100/P1100), but it can be set to operate as follows: OPTION DESCRIPTION 0 = Default mA output relative to Mode P100/P1100 1 = Distance mA output relative to Distance. 2 = Level mA output relative to Level. 3 = Space mA output is relative to Space. 4* = Average Level mA output is relative to the Average level. 5* = Differential mA output is relative to Differential level

109

SLUDGEFINDER 2 INSTRUCTION MANUAL

Setpoint By default, the mA Output will represent the empty (0 or 4mA dependant on (P830/P890) mA Range) and 100% of the operational span (20mA), but you may wish to have the output represent a section of the operational span. For example, the application has an operational span of 6 metres, but output is to represent empty (0 or 4mA dependant on (P830/P890) mA Range) to a level of 5 metres (20mA). If so P834 (Low Level) should be set to 0.00 metres and P835 (High Level) should be set to 5 metres. P1-834, P2-892 mA Low Level This parameter sets the level, distance, or space, depending on the selected mA Out Mode (P831/891) at which the low mA output will occur (0 or 4mA dependant on (P830/890) mA Range). Default = 0.000m P1-835, P2-893 mA High Level This parameter sets the level, distance or space, depending on the selected mA Out Mode (P831/891) at which the high mA output will occur (20mA). Default = 6.00m P1-836, P2-894 mA Low Limit This parameter sets the lowest level that the mA output will drop to, the default is 0mA, but you can override this if the device you connect to cannot for example accept less than 2mA, yet you want to use the 0-20mA range. Default = 0.00mA P1-837, P2-895 mA High Limit This parameter sets the highest level that the mA output will rise to, the default is 20 mA, but you can override this if the device you connect to cannot for example accept more than 18 mA, yet you want to use the 0-20 mA range. Default = 20.00mA 1-P838, P2-896 mA Low Trim If the device you are connected to is not calibrated, and not showing the correct low value (reading), then you can trim it using this parameter. You can either type in the offset directly or use the arrow keys to move the output up and down until you get the expected result (reading) on the device that is connected.

110 PULSAR MEASUREMENT

P1-839, P2-897 mA 1 High Trim If the device you are connected to is not calibrated, and not showing the correct high value (reading), then you can trim it using this parameter. You can either type in the offset directly or use the arrow keys to move the output up and down until you get the expected result (reading) on the device that is connected. P1-840, P2-898 mA Failsafe Mode This parameter determines what happens to the mA output in the event of the unit going into fail-safe mode. The default is to do the same as the system fail-safe (P808), but this can be overridden to force the mA output to an independent fail-safe mode as follows: OPTION DESCRIPTION 0 = Default mA output will fail as per P808/P1808 1 = Hold mA output will retain its last known value. 2 = Low mA output will fail to its low condition. 3 = High mA output will fail to its high condition.

P841 mA Allocation By default, the mA output will be representative of the reading obtained, as determined by the Mode P100/P1100. When P100/P1100 = 4 (Average) or 5 (Differential) the mA output can be assigned to be representative of the level of either of the two points of measurement This parameter is automatically set to the correct default option when selecting the Mode P100/1100 and Xducer (P101/P1101), and under normal circumstances will not require changing. The options, dependant on the value entered for Mode P100/P1100, are as follows: OPTION DESCRIPTION 1 = Xducer 1 (Default P1) mA output relates to Xducer 1 level 2 = Xducer 2 (Default P2) mA output relates to Xducer 2 level

111

SLUDGEFINDER 2 INSTRUCTION MANUAL

Compensation Parameters Offset P1-851, P2-851 Measurement Offset The value of this parameter is added to the measured distance, in Measurement Units (P104). This Offset will be added to the level, as derived from the transducer, and will affect everything including the reading on the display, the relay setpoints and the mA output.

Temperature P1-852, P2-1851 Temperature Source This parameter determines the source of the temperature measurement. By default, it is set to automatic (P852/P1852=1), which will automatically detect if a temperature sensor is available from the transducer. If for any reason, no temperature input is received, then the Fixed Temp value is used, as set by P854/P1854. The temperature source can be specifically set as follows: OPTION DESCRIPTION 1 = Automatic (Default) Will automatically select transducer temperature sensor, if available, or fixed temperature (P854) if no temperature sensor found. 2 = Xducer 1 Always uses temperature reading from transducer 1. 3 = Xducer 2 Always uses temperature reading from transducer 2. 4 = Fixed Always uses fixed temperature (P854/P1854)

P1-P854, P2-P1854 Fixed Temperature This parameter sets the temperature, in degrees Celsius, to be used if P852/P1852 (Temperature Source) =3. Default = 20oC P1-P860, P2-P1860 Sound Velocity This parameter allows for the velocity of sound to be changed according to the atmosphere the transducer is operating in. By default, the velocity is set for sound travelling in air/water at an ambient temperature of 20 degrees centigrade. Default = 342.72m/s (velocity in air for dB transducer) Default = 1482.32m/s (velocity in water for VT transducer)

112 PULSAR MEASUREMENT

Stability Parameters Point 1 / Point 2 Damping Damping is used to damp the display, to enable it to keep up with the process but ignore minor surface fluctuations. P1-870, P1870 Fill Damping This parameter determines the maximum rate at which the unit will respond to an increase in level. It should be set slightly higher than the maximum vessel fill rate. Default = 10m/min. P1-871, P2-1871 Empty Damping This parameter determines the maximum rate at which the unit will respond to a decrease in level. It should be set slightly higher than the maximum vessel empty rate. Default = 10m/min. Filters The following three parameters can be used to filter out unwanted changes of level caused by a ‘rippled’ or agitated surface. P1-881, P2-1881 Fixed Distance This parameter determines the width of gate to be used in tracking an echo and under normal circumstances will not require changing, but it can be increased in the cases where the surface is moving extremely fast (in excess of 10m/min) to ensure smooth processing of the changing level.

P1-882, P2-1882 Process Filter (dB Transducers) This parameter determines the number of ‘cycles’ that will be taken before a change in level is processed and the display updated. OPTION DESCRIPTION 1 = Fast level will be updated every cycle 2 = Medium level will be updated every 8 cycles 3 = Slow (Default) level will be updated every 16 cycles

113

SLUDGEFINDER 2 INSTRUCTION MANUAL

P1-883, P2-1883 Gate Expand This parameter determines the size of the increment by which the gate expands per cycle when an echo is detected outside of the gate. Default = 0.1m

Echo Processing Parameters Point 1 / Point 2 Transducer 1 Status P1-900, P2-910 Transducer Status This parameter shows the current state of the transducer. The value means the following: OPTION DESCRIPTION 0= OK Transducer working correctly. Transducer is not being used (mA input is being 1= Disabled used instead, so P101=1) Indicates that the power and signal lines on the 2= Stuck High transducer terminals are crossed over, or the signal line is shorted to earth. 3= Not Found No transducer is detected.

P1-901, P2-911 Echo Confidence 1/2 This parameter displays the most recent echo confidence from the transducer. It is useful to help find the best mounting location for the transducer, where you should aim to get the highest figure. It is a percentage of confidence that the echo reporting the level is the correct one. P1-902, P2-912 Echo Strength 1/2 This parameter displays the most recent echo strength figure for the transducer, where a higher figure indicates a better returned echo. P1-903, P2-913 Average Noise 1/2 This is the mean noise reading for the transducer. It is measured while the transducer is not firing and gives an indication of the average amount of electrical noise present on the cabling.

114 PULSAR MEASUREMENT

P1-904, P2-914 Peak Noise 1/2 This is the peak noise reading for the transducer. It is measured while the transducer is not firing and gives an indication of the maximum amount of electrical noise present on the cabling. P1-905, P2-915 Sensitivity (dB Transducers only) This parameter determines the sensitivity of the unit. Please consult Pulsar for further information and assistance on changing the value of this parameter. P1-906, P2-916 Side Clearance (dB Transducers only) This parameter is used to set the distance by which the DATEM trace will “stand-off” from around unwanted echoes such as obstructions. Please consult Pulsar for further information and assistance on changing the value of this parameter. Default 5dB (50mV)

Date & Time The date and time is used, to control specific relay functions and date stamp certain events that are contained in the Data Logs. It is also used in conjunction with the system watchdog that keeps an eye on the times the unit has started. P931 Date This parameter displays the current date, in the format as set by P933 (Date Format) and can be reset if required. P932 Time This parameter displays the current time and can be reset if required, in the format HH: MM (24-hour format). This is set initially at the factory for UK time. P933 Date Format This parameter allows you to alter the format that the date is displayed to your choice of DD: MM: YY, MM: DD: YY or YY: MM: DD. The default is DD: MM: YY.

LED Colour Each relay has an associated LED, located on the unit’s front panel, which indicates the status of the relay. By default, the LED of any relay that has been programmed but is in its “OFF” state will be illuminated ‘yellow’. When “ON” alarm relays will cause the LED to illuminate Red and pump, control and miscellaneous relays will cause the LED to illuminate green. LED’s of any relays that have not been programmed will not be illuminated. Customised settings for the colour of LED’s can be achieved by using the following parameters.

P935 Off Relay Colour This parameter selects the colour that a programmed relay should be when it is in its “OFF” state. The default is 3 = yellow, but can be changed to ‘no colour’, red or green. P936 Alarm Relay Colour This parameter selects the colour that an alarm relay should be when it is in its “ON” state. The default is 1 = red, but can be changed to ‘no colour’, green or yellow.

118 PULSAR MEASUREMENT

P937 Pump Relay Colour This parameter selects the colour that a pump relay should be when it is in its “ON” state. The default is 2 = green, but can be changed to ‘no colour’, red or yellow. P938 Control Relay Colour This parameter selects the colour that a control relay should be when it is in its “ON” state. The default is 2 = green, but can be changed to ‘no colour’, red or yellow. P939 Miscellaneous Relay Colour This parameter selects the colour that a miscellaneous relay should be when it is in its “ON” state. The default is 2 = green, but can be changed to ‘no colour’, red or yellow. All relays that are not programmed will show, ‘no colour’, i.e. they are off.

Watchdog You can check how many times the unit has been switched on, and look at the date and time of the last ten starts. This can be useful if there have been power failures or if for any reason the Sludge Finder 2 restarts due to a fault condition. The Sludge Finder 2 can be backed up from a battery which automatically cuts in during power failure. Battery backed up units will continue uninterrupted operation and therefore will not register a loss of mains power. If, however, the battery was to fail during a mains power interruption, a start up would be recorded once power has been restored. P940 Number of Starts This parameter shows how many times the unit has been powered up. P941-P960 Start Date & Time Parameters P941 and P942 show the date and time that the unit was last started. There are ten start dates & times recorded, which are parameters P943-P960. The first on the list are the most recent, and the last ones are the oldest. These are read only and cannot be changed.

124 PULSAR MEASUREMENT

Test Parameters Simulation P980 Simulate Test mode is used to simulate the application and confirm that all parameters and relay setpoints have been entered as expected. During simulation, there is a choice of whether the relays will change state (hard simulation) or not (soft simulation), but the LED’s will always change colour as programmed, and the current output will change. If you want to test the logic of the system that the relays are connected to then select a hard simulation, but if you do not want to change the relay state, then select a soft simulation. There are two simulation modes, automatic and manual. Automatic simulation will move the level up and down between empty level or the pre- determined Start Level (P983) and Pump/Control relay switch points, if you wish to change the direction of the level movement e.g. to go beyond relay setpoints, this can be done by using the arrow keys. In manual simulation, using the arrow keys will allow you to move the level up and down as required. The choices for you to enter are as follows. 1= Manual soft simulation 2= Automatic soft simulation 3= Manual hard simulation 4= Automatic hard simulation Whilst in Automatic hard simulation (P980 = 4) the switching of digital inputs can be simulated by pressing the corresponding numeric key to the input to be switched, each time the numeric key is pressed it will toggle the input between On and Off. To return to program mode, press ‘CANCEL’ and test mode will end. P981 Increment By default, simulation mode will move by 0.1m steps in manual simulation and by 0.1m/min in automatic simulation. Altering the increment can change this value.

125

SLUDGEFINDER 2 INSTRUCTION MANUAL

P982 Rate In automatic mode, the rate at which the level will move up and down, is determined by distance, P981 Increment and the time, P982 Rate which by default is set to 1min and can be changed as required. To increase the rate at which the level moves increase the Increment (P981) or decrease the Rate (P982). To decrease the rate at which the level moves decrease the Increment (P981) or increase the Rate (P982). P983 Start Level When using automatic simulation this parameter can be used to pre- determine the point at which the simulated level will start at and return to. This can be used to simulate the lowest point to which the level would normally operate. Hardware P990 Self Test If you enter 1 for this parameter, then the unit will perform a self-test. This will confirm that the various parts of the circuitry are working correctly. You will see confirmation messages that the clock and the EEPROM are working correctly, and error messages for any parts that fail.

126 PULSAR MEASUREMENT

P991 Hard Test When this parameter is selected, the unit will test the following in turn. • LED’s. Watch them change colour as shown on the display, and press, ENTER, if they operated as shown. • Relays. Press a numeric key corresponding to the number of the relay you wish to test, and the relay will change state each time the key is pressed. If you press any other key, other than a valid relay number, then the test will end. • Segments. All the segments on the LCD are lit up, so you can see if they all work.
